Barack Obama, SF fan?

Fascinating to see that [Obama is reading Seveneves this summer](https://www.whitehouse.gov/blog/2016/08/12/presidents-summer-reading-list), by my [design hero Neal Stephenson](http://bob.ryskamp.org/brain/?p=4150). Another example of the massive impact that fictional storytelling can have on the world, through the people who read it.
